My last working day of 2007

[Jack.Chu]

Hello guys:
I created a simple tool to count how I wasted my time day by day ;-)

It's simple, a small program running on background, logging the title
of foreground window. A python script parses the log file and then
generates chart by matplotlib.

I just want to get suggestions to improve it, or know the news that
somebody had implemented a better one so I can abandon my toy.

thanks.
